如何使用新行或行尾将 mysql 数据库中的字符串分成两部分？

Question

我有一个从可能有多个换行符的数据库字段中设置的变量。我想要一些 php 代码，仅使用第一个换行符作为分隔符，将文本从该变量拆分为 2 个单独的变量（或具有 2 个值的数组）。

所以你明白我想做什么，变量来自的数据库字段是一条 post 消息，我基本上想使用文本的第一位到第一行中断作为post 标题和之后的所有内容作为 post 消息。

示例如下：

$myvariable = "Do you believe what happened today?\nThis great big bus almost ran me over. Then I jumped out of the way.\nThen something else happened and it was more crazy.\nFinally I decide to go home and have a nap because the day was just going too crazy.\nI like elephant pants, the fit me\nSNUGG!";

My new variables would become:

$title_from_myvariable = "Do you believe what happened today?";

$message_from_myvariable = "This great big bus almost ran me over. Then I jumped out of the way.\nThen something else happened and it was more crazy.\nFinally I decide to go home and have a nap because the day was just going too crazy.\nI like elephant pants, the fit me\nSNUGG!";

我研究了几种使用 \n 作为分隔符并使用 explode 来执行此操作的方法，我还研究了 PHP_EOL 使用 explode。

有一些关于此的很棒的话题，如下所示：

问题是如果我使用如下代码：

$new_array_with_new_variables = explode("\n", $myvariable);

或

$new_array_with_new_variables = explode("PHP_EOL", $myvariable);

我最终将 EVERY 新行拆分为一个变量...

超级程序员有什么建议吗？我就是想不通这个！

Answer 1

以下将满足您的需求。

$new_array_with_new_variablesTMP = explode("\n", $myvariable);
$new_array_with_new_variables = array($new_array_with_new_variablesTMP[0]);
array_shift($new_array_with_new_variablesTMP);
array_push($new_array_with_new_variables, implode('\n', $new_array_with_new_variablesTMP));

print_r($new_array_with_new_variables);

结果：

Array
(
    [0] => Do you believe what happened today?
    [1] => This great big bus almost ran me over. Then I jumped out of the way.\nThen something else happened and it was more crazy.\nFinally I decide to go home and have a nap because the day was just going too crazy.\nI like elephant pants, the fit me\nSNUGG!
)

这是一个有效的方法。

<?php
$pieces = explode("\n", $myvariable);
$title_from_myvariable = $pieces[0];
$message_from_myvariable = implode("\n", array_slice($pieces, 1, count($pieces) - 1));
